This depends mostly on the amount of mailboxes and mails you have. Bear in mind, that mail is usually composed of many many small files. Many small files take longer to copy than one large file. A full (or first) backup takes much longer than successive (incremental) backups. The amount of time necessary for a full backup can vary from minutes to hours.
